Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention is directed to various contaminated water used on the golf course premises, particularly contaminated water containing pesticides such as herbicides and other chemicals.
It aims to provide a new water quality management structure and a new water quality management system using it to prevent the water from flowing out of the site.

[Prior Art] With the rise of living standards, the golf population of our country has also increased significantly, and the concept that golf is a luxury sport like that of a time has been completely wiped out.

In response to such changes in lifestyles, new golf courses are being established around the metropolitan areas and around the local cities. And this tendency has been further spurred by the motivation of resort development nationwide, spread to mountain towns and villages rich in nature, and we have partnered with private capital as a major pillar to achieve revitalization of the area. Many places are launching golf course construction plans.

This golf course is a healthy recreational facility where people can enjoy their lives, dreaming many people, and playing a major role as one of the leaders of regional revitalization, while recreating the expansive nature. Contamination of surrounding water sources by various chemicals such as pest control, pesticides for control, pesticides for weeding, fertilizers for turf cultivation, etc., in addition to the problem of nature conservation, especially recently. Other environmental pollution problems have come to be widely discussed, and the treatment of these environmental pollution problems is of great concern not only to the parties involved in development but also to the residents and workers who will be located in the vicinity. It has become a thing.

Several solutions have been proposed and implemented for the golf course or the construction thereof that has had such social problems. One is the solution from the side of the drug used, and the other is the solution from the side of the facility called the golf course.

The solution on the side of the former drug is the development and research of toxicity mitigation of the drug itself used, regulation of its handling standard,
It is a solution to reexamine, that is, to reduce the damage when entering the surrounding environment as much as possible, and it can be said that it is a difficult solution to achieve complete harmlessness.

On the other hand, in the latter, the solution from the facility side, for example, the Purr-Wick System = Plastic-barrier Under Reservoi
The water management system called r Root-zone With Wick Action System) was further improved and developed like a method of development, "35 to 45 cm in height at an appropriate interval on a predetermined dug base. After erection of the partition plate of, the plastic sheet is laid along the base including the partition plate and the water retention device is applied, while the drain pipe is placed at the position above the plastic sheet at the base of the partition plate. Roll it down and spread river sand as floor soil on it, and use the capillary force of the sand to supply a stable amount of water to the turfgrass, as well as drain excess water (containing various drugs) with a drain pipe. It collects water, treats the contained chemicals with a purification device, and directly discharges it without passing through a collection pond or the like. "An excellent system that consistently manages water supply and water purification Has been realized by adopting As can be seen in many golf courses (already appearing all over Japan), the water that flows out of the golf course grounds is treated as clean water that does not cause pollution inside the golf course grounds. The solution from the facility side may ensure that the pollution problem can be avoided by devising a mechanism to complete the golf course as a facility.

Based on the above knowledge, this invention also reviews the golf course from the side of the facility, and develops a new facility structure and a system using it, so as to completely clear the pollution problem that cannot be avoided when constructing the golf course. The configuration is as described in detail below.

(Structure of the Invention) As can be clearly understood from the typical embodiment shown in the drawings, the water quality management structure on the golf course grounds, which is the basic invention of this application, has the following structure. .

That is, in the geological structure of the entire golf course site, along the site boundary part 5 on the downstream side of the slope structure of the impermeable layer part 2 such as the clay layer or the clay layer or the rock layer, The water quality control structure on the golf course site is formed by forming the water blocking wall or the water blocking film 1 reaching the layer 2.

In the impermeable layer part 2, after grasping the exact stratum cross section of the golf course construction site by means of appropriate geological exploration means such as boring, sound waves, earthquakes, etc. Alternatively, if they do not exist and the bedrock layer is present in a relatively shallow part, such a bedrock layer that does not allow permeated water from the surface 4 to pass through to the layers below it. It will be discovered by defining the parts, and the inclination structure of each layer will be elucidated in the exploration process.

The impermeable wall or the impermeable film 1 is a structural portion that blocks the flow of water moving below the surface of the earth 4, and the impermeable wall is, for example, a concrete wall or a sheet pile having a leak-proof structure. Various plastic sheets without pinholes are adopted as the water film, which is the impermeable layer part 2 in the stratum structure found above, and is the downstream side along the site boundary 5 in the slope structure. A continuous structure from the ground surface 4 up to the part is realized.

By the impermeable wall or the impermeable membrane 1 thus formed, the permeated water flowing along the impermeable layer portion 2 is blocked within the boundary of the site, and the permeated water is accumulated on the impermeable layer part 2 within the site. The so-called underground dam 3 will be formed. as a result,
Water containing various drugs used for golf course management,
The water quality that uses this golf course water quality management structure is to be surely prevented from penetrating into the ground and becoming groundwater that flows out of the golf course premises and contaminates the water sources in the surrounding area. Regarding the management system, it is assumed that one of the basic configurations and specific examples is given.

(Other related invention 1) The water quality management system on the golf course site of the present invention forms the underground dam 3 by the seepage water in the stratum above the impermeable layer part 2 by the water quality management structure on the golf course site described above. Then, the permeated water containing various components stored in the underground dam 3 is pumped up and reused as water for golf course management,
Various permeated water that permeates the golf course premises is enclosed and circulated in the premises.

Based on the embodiment shown in the longitudinal sectional view of FIG. 1 and the arrangement view of FIG. 2, the configuration will be more specifically described as follows.

(Example 1) Impervious portion 2 on the golf course site found by the geological exploration result
The downstream side of the inclined structure is the house and other facilities shown in Fig. 2.
If the upper left corner of the area dotted with 6, ... is located along the valley in the shape of the ground, the impermeable wall 1 extends over a predetermined area inside the site boundary 5 around that area, as shown in FIG. Are formed by, for example, pouring concrete.

As a result, an underground dam 3 is formed in the golf course grounds on the upstream side of the water impermeable wall 1, as shown in FIG. The permeated water containing various drugs that has permeated from the ground surface will not be discharged.

Inside the golf course grounds, where the pumping pipe P1 reaches the underground dam 3 formed in this way, and the pumping pump P is used to pump the water at any time, and then the pumping pump P1 flows alone or in a deeper layer as shown in the figure. Groundwater that is not related to the seepage water is also pumped by the water pipe P2, mixed, and reused as water for golf course management by the water distribution pipe P3 that connects the green side and other necessary parts. As a result, the water containing various drugs used on the premises will be circulated and utilized almost permanently only on the premises, in other words, used on the premises that penetrate with the various drugs contained. The water will not be able to flow out of the golf course premises no matter how long.

In addition, as for the management of the water that flows out beyond the site boundary 5 on the ground surface 4, as shown in the drawing, a U-shaped groove U should be installed, or other known means should be adopted. Therefore, the inside and outside of the site will be insulated on the flow of water.

(Other related invention 2) The following invention relates to another water management system utilizing the water quality management structure on the golf course premises, which is the basic invention of the present invention described above, and particularly when the degree of pollution becomes severe. The invention is characterized in that an expected section and a less-significant section are managed separately.

That is, as shown in FIG. 1 of the drawing, among the tee ground T, green G, fairway F, rough R, and catchment S of the golf course, particularly in the section that is necessary for contaminated water management. , Forming a water-blocking sheet layer 7 that separates a portion from the predetermined underground depth to the surface of the earth in a bowl shape, and the permeated water in the section separated by each water-blocking sheet layer 7 is guided to a predetermined catchment S The stored water is appropriately purified and then discharged or reused. On the other hand, the permeated water inside the golf course premises outside the section separated by the water-blocking sheet layer 7 is the same as in claim 2. The water quality management system is a water quality management system on the premises of a golf course that is enclosed and managed on the premises.

This system is as follows by showing a more concrete example.

(Embodiment 2) As shown in the vertical cross-sectional view of FIG. 1, the tee ground T and the green G portions, which are the sections particularly required for contaminated water management, are dug to an appropriate depth according to their planar shape. Water-impervious sheet layer 7 along with the ground
And a plurality of drain pipes P4, P4, ... are horizontally provided on the water-blocking sheet layer 7 (in the embodiment, the drain pipes are arranged radially from the center of the dug hole). The drain pipes P4, P4,
One end side of …… shall be able to be collectively guided to the catchment S by the catchment pipe P5.

The purifying device 8 and the capillary trench 9 on the downstream side of the purifying device 8 are provided on the downstream side of the water collecting basin S.

Normally, in tee ground T and green G, it is necessary to carefully manage the turfgrass in more than other sections of the golf course, so special fertilizers, herbicides and other chemicals are regularly provided in other sections. Water is sprayed and sprinkling work is carried out without fail. Therefore, naturally, the drug and the water containing them are present in those compartments at a density higher than that of the other compartment parts, and permeate underground.

Therefore, in order to manage these contaminated water, only those areas that are particularly necessary for management should be managed independently from other areas.
For example, by combining the structures and devices as described above, water and chemicals that are neither absorbed nor evaporated by turfgrass in these compartments become permeated water containing the chemicals and gradually descend and permeate. And some of them are drain pipes P4, P4 ……
From the above, the others are made to reach the water-blocking sheet layer 7 so as to prevent the water from flowing thereover and permeating to the water-blocking sheet layer 7 or less, and while guiding the water to the water reservoir S through the water collecting pipe P5 and storing it. While those that settle are allowed to settle and separate, the other ones decompose and purify organic substances such as pesticide components and fertilizer components by the purification device 8 disposed further downstream, and then lead to the capillary trench 9 to anaerobically. Although it is purified by using bacteria, it is either diffused in the soil or not shown in the figure, but it is stored separately in a reservoir or the like and reused as management water.

On the other hand, the permeated water that has been infiltrated by the chemicals used for controlling the rough R, the forest bush M, etc. other than the above-mentioned compartments is the water quality using the basic water quality management structure of the present invention. With the management system, it is enclosed within the site boundary 5,
Try to use it cyclically.

In this way, a new system is realized in which the water quality of the golf course is efficiently managed by dividing the inside of the golf course into reasonable means according to the pollution state.

(Function and Effect) In the water quality management structure on the golf course site of the present invention having the above-described configuration, the permeated water contaminated by the chemicals used on the golf course site flows out as the groundwater to the outside of the site boundary 5. , A structure that does not contaminate the water sources such as surrounding private houses and facilities 6, 6, ... can be realized by the extremely rational and reliable structure of forming the impermeable wall or the membrane 1. Moreover, in terms of its economic burden, it is never a disadvantage in terms of the total golf course construction cost, and therefore it can be said that it is very effective as a pollution control means for guaranteeing a safe living environment.

In particular, the water impermeable wall or membrane 1 structure, which is one of the water quality management systems utilizing this basic invention, encloses the groundwater containing the chemicals in the impermeable layer part 2 on the golf course site In the water quality management system, where the dam 3 is formed and the groundwater containing the chemicals is pumped up again to the surface and reused as water for turfgrass management, the turfgrass is gradually absorbed and digested during this circulation process. In addition to having the excellent feature that the purification action will be utilized and the above-mentioned effectiveness as a pollution control measure will be more reliably demonstrated, in addition to just ordinary groundwater Compared to the conventional watering that was relied on, the groundwater to be used will be watering in the state that already contains chemicals useful for plants such as turfgrass, so it is advantageous for turfgrass growth by itself. Not only that, the amount of newly used chemicals such as pesticides and fertilizers can be reduced by that amount, which obviously leads to an advantage in terms of golf course maintenance costs, and further spreads in the natural world. This has a very important effect of being beneficial in reducing the absolute amount of harmful substances themselves.

In addition, the sections with different degrees of pollution on the golf course premises are divided into sections according to the degree of pollution, and in the case of sections with a high degree of pollution, purification means that distinguishes this section from other sections is used to improve purification efficiency. On the other hand, for the other sections, another water quality management system that manages water contaminated by the water quality management system using the above-mentioned basic water quality management structure of the present invention improves water purification efficiency. Needless to say, it will lead to measures to reduce the risk of contaminated water flowing out of the golf course grounds, and as a result, safety in terms of pollution control will be assuredly guaranteed, and in terms of achieving the purpose of the present invention. It can be the most effective one.

As described above, the golf course water quality management structure and the water quality management system using the same according to the present invention are extremely effective in economically and reliably solving the pollution problem of water pollution associated with resort development which has been particularly problematic in recent years. It is expected that the present invention will be extremely effective in promoting resort development, which is a means and a major pillar of regional revitalization.
